Orange pi 5 Ultra and pwm

[Erez Alster]

Hi

I'm trying to use Armbian with Orange pi 5 Ultra. 
So far so good  The hdmirx is working great!

I'm not able to control my gpio pins with PWM in equivalent to orange pi 5 ultra image. I guess that i need to load additional overlays, Am I correct?

Please review the armbian logs here:
https://paste.next.armbian.com/nekodihico

I also noticed that pin numbers were changed if I compare it to the Orange pi OS.
 

Thanks in advance!

The image you are using is intended for 5 max instead of 5 ultra?

[Erez Alster]

yes.

I copied the dtb from orange pi 5 ultra official image and copied it.

[Werner]

So you are using a device tree for a different device and complain that things don't work as expected?

[Erez Alster]

I'm not complaining at all....
I'm wondering how I can debug it.

I'm able to use the same device tree with the official orange pi os.

Well on the bright sight both max and ultra are very similar.

Though overlays might differ but that would need investigation. Easiest route is the one you actually already got on by checking the vendor source. Maybe they also provide a handful of matching overlays for this board. Maybe they can be ported.

Hello Erez Alster, im on the same page, but the issue is that im trying to get PWM to work using ubuntu that is from the orangepi wbesite, did you get it working? if yes, can you share with me how you got the pwm to work? for me, it blinks and its very choppy! thanks in advance.

I'm using the gpio cli. nothing else worked for me

[Erez Alster]

I was able to make things work. i had bad configuration
So everything is working correctly.

I've another issue. I've the following errors in dmesg

Something I'm able to use the HDMI input and sometimes i'm not. Any idea what can be the issue?

The hdmirx is covered in different thread.
I will continue there
